IMPROVEMENT IN RAILROAD-CAR. STOVES.

The Schedule referred to ln these Letters Patent and making part of the dame,

To all when; it may concern:

Be it .known that I, JOHN OhllllANT, of Spring Hill Furnace, in the county of Fayette and State of Pennsylvania, have invented new and useful .lmprovements in I-Railroad-Stoves and Regulators; and I dohcreby declare the following to be a full, clear, and exact description thereof, sufficient to enable others skilled in the art to which my invention appertains to make and use the same, reference being bad to the accompanying drawing forming part. of this specification, in which- Figure 1 is a front view of my improved railroadstove and regulators.

Figure 2 is a section of the same, showing the coustruct-ion of the water-chamber, sectional-ring, firechambcr, and valve arrangements.

Figure 3 is a detached view of the grate.

Nature and Objects of the Inrent-ion.

This invention relates to that class of stoves dosigncd for use on railroml-cars; and

It consists- First, of a reservoir adapted to contain a quantity of water or other liquid, surrounding a metallic cylinervoir, and acting as indicator, fora purpose hereinafter mentioned.

Description. 1 represents the top, and \V the lower portion or base of the stove, formed either of wrought or castiron, or other suitable metal, and are made prcferzu bly of a cylindrical form.

The upper portion of the top part of the stove is -li1nnc1-shaped, and terminates in an opening or pipe, N, for the reception ofsuitablc pipe or pipes to allow the smoke or cindcrs to escape,

\Yithin the opening or pipe N is located or formed a. guide-plate or frog, 0, provided with an opening which supports and directs a rod carrying a valve, 0, for a purpose hereinafter mentioned.

1 is a metallic cylinder or other shaped lining, preferably of cast-iron, constructed within the interior of the lower portion or base \V of the stove, and extends up to a point about where the parts L and \V unite.

13 is the fire-chamber, located within the upper portion of the met-allinlining 1, and which is provided with a grate, ll.

1* is an opening in the lower portion or base \V of the stove, which permits the fire in the fire-chamber to be easily stirred.

It is a'movable ring formed in sections, (althoughit may be made in one piec having its bearings upon the top part of or flanges formed upon the side of the iron cylinder or lining 1, its sides fitting closely upon the inner circumference of the top part of the stove L, so as to prevent any ashes from falling or passing into a chamber or reservoir, A, at the same time preventing water from being Tdashcdinto the lire-chamber, caused by the jerks and jars to which cars are subjected. This ring is made preferably in sections, so that one or more of the pieces will easily and surely be displaced should the stove be 'upset; they being held in their proper place by the pressure of the fuel upon them when the stove is in an upright or vertical position;

A is the water-chamber or reservoir, formed by the inner metallic cylinder or lining P and the outer casing of the stove W. This chamber or reservoir is provided with suitable opening for cleansing it, should it by any means receive in it foreign substances.

An orifice, a, and pipe, I, are formed. with this chamber or reservoir A, for filling the same with water and permitting vapor to escape.

\Vithiu this orifice a and pipe I is located, and freely moves up and down, a valve or float, R, made of cork, wood, or suitable material, and is attached to a rod extending some distance above the top of the pipe, so that, as the water becomes low in the chamber or reservoir, the descent of the rod will indicate to the attendant in charge, or passengers, that the chamber or reservoir needs replenishin This valve or float R performs another important function; that is, when the stove by accident is upset, securely closing orifice a and supply-pipe I, thus preventing the water from escaping through it, causing the same to pass the space from which the movable ring has fallen, and immerse the fire which has fallen in the upper part of the store I), the valve 0 in the pipe N being closed by the fuel falling upon it.

S is a pipe located beneath the grate H in the met-allic cylinders or lining comiecting with the chamber or reservoir A, and has formed with it or otherwise secured, an upright orifice or pipe, V, at or near its center, so as to facilitate the immediate action of the water on every portion of theiire when the stove is upset. This tube or outlet Y is covered by a plate attached to the grate H.

M isan out-side fender or jacket covering theupper portion of the stove, to prevent combustible material from coming in contact with the hot surface of the stove, and also, to give, by its various configurat-ions, a neat appearance to the stove. This jacket is provided with an opening corresponding to the door in the stove through which the fuel is fed tofthc' fi re-chamber.

If it-be desired to carry more waterand efiectually guard against accident and its dashing out, the me? tallic lining may be extended up nearly to the top of the stove, as indicated by 1), dotted lines, in which case the outer casing of the lower part of the stove is extended up to a point about as high as the extended partot' the metallic cylinder or lining p'findicated by the letter X. 1 4

The movable ring 1*] is then placed upon the top of the metallic lining, in a similar manner, as before described. 7 o 4 a VVh'en the water-chamber or reservoir is extended, as shown in the dotted lines indicated by X, the connecting pipe S with its appendage may be dispensed with.

In either state, it will readily be observed that in case of the stove being upset, the water in the chamor' reservoir A, forces the valve or float R close against the orifice or supply-pipe, the fire in the firechamber fitllsforwa-rd into the funneled portion of the top part of the stove, and closes the valve 0 in the pipe N, and the movable ring falling from its proper position, the entire contents of the chamber or reservoir A are poured upon and effectually extingnish the fire.

Vhen the stove is thus constructed, it is mounted upon or secured to suitable feet.

T T are pipes connected with the lower portion of the stove, which are designed to extend along the sides of the car in a chamber, or recess if desired, for the purpose of conveying heated steam or water, thus more uniformly distributing the heat. These pipes will be connected with automatic valves or cocks of the usual construction, so as to' close should an accident occur. A register maybe provided at each seat in the car, if desired, or if used as astationary regulator, the pipes may be extended into other lOOlllS.

It will also be understood that this device may also be applied to locomotives by dispensing with the lower portion of the ash-box, and using itas a reservoir or chamber for containing water, to be brought in contact with the fire should the stove be upset.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. The reservoir A surrounding the fire-chamber, and made to communicate with the interior thereof by means of the removable plate E, substantially as described.

2. The ring E in the ire-chamber, applied to operate substantially as described.

3. The float-valve R in connection with the reservoir A.

4. The tube S, communicating with the reservoir A and the tire-chamber, substantially as and for the purpose described.

To the above I have signed my name this 19th dayof l\:[ay, ]870.
